A polymer tube 2.5mm diameter with a Youngs Modulus = 2 GPa that contains a metal rod diameter<br>
0.75mm with a Young's modulus of 107 GPa. I need to know the overall bending stiffness of the<br>
assembly. <br>

If both materials were touching it would be simple i.e. <br>
<br>
k = EI , where I =...
can someone tell me how to calculate the best value (ie lowest weight for a given stress) value for t/r for a straight tube loaded: in pure tension, and pure bending?<br>
